To all whom, '1lb may concern.- Similar numbers denote the same parts inBeit known that I, DAVID T.

It should be noted (seeFigs. 5 and 6) that the outer edge of opening 14 corresponds in widthwith opening 5 in the outer cone, with which it registers, but that saidopening 14 curves outward on both sides and has at about its centralportion a much greater width than at its outer edge. The purpose of thisconstruction will presently be fully explained. The lower end of theinner cone is solid and extends down into opening 4. The parts aresecured together by a screw, 16, which passes through a washer, 17,resting upon the base of the outer cone and engages the inner cone. Theparts are thus held firmly together; but theinner cone is left free torotate within the outer cone when it is desired to change the quality ofthe stream. The lower end of the inner cone is preferably made angular,as indicated at 12-, and the interior ot the washer made to correspondtherewith, so as to prevent the latter from turning. The outer end ofthe tube is provided with a lscrew-thread, 18, and a stop, 19.

20 denotes the cap-plate, which nearly closes the outer end of the chamber, a narrow circular opening, 202, being left between the cap-plateand flange, through which the water passes in forming the ribbon-spray.An opening, 21, is provided at the center of the cap-plate, which isinternally screw-threaded to engage thread 18 upon the tube, a hub, 22,being preferably formed on the inner side of the capplate to engage stop19, as clearly shown in Figs. 1 and 3.

In Figs. 1 and 3 the circular opening between the eapplate and tiange isexaggerated for clearness. In practice the cap-plate acts as a stop tolimit the outward movement of the adjustable flange, the upper knurlacting as a stop to limit its inward movement. The operation may beclearly understood from the drawings.

Suppose that it is desired to prod uee a straight stream. The barrel isrotated until opening 14 in the inner cone,which leads into the tube, isbrought to register with opening 5 through the side of the outer cone.This allows the water to pass freely from the base out through the tube,which ofcourse produces a straight stream. The position of the severalpartsin producing this result is clearly shown in Figs. 1 and 5. Toproduce a central spray it is simply necessary to turn the barrel andinner cone sufficiently so that the outer cone partially covers opening14, as clearly shown in Fig. 2, This partially cuts off the ow,

thereby increasing the pressure, and forces the water to pass through4the openings at an angle and to pass partially around opening 14, theinterior of which is enlarged, as already explained, before it can passinto tube 5, so

that the stream is given a spiral movement in said tube, which breaksthe stream and causes it to pass out therefrom in the form of spray. Theamount of water thrown and the lineness of the spray are perfectlycontrolled by turning the barrel slightly in either direction. When itis desired to produce a very fine spray, or, on the other hand, to throwin the form of spray a greater volume of water than is possible throughthe tube, either result in ay be accomplished by giving the barrel apartial turn to the position shown in Fig. 3. This cuts offthe flow intothe tube,but permits an unobstructed flow from the base, throughopenings 5 and 13, into the chamber in the barrel, and thence out in theform of a. circular ribbon-spray between the flange and eapplate. Asalready explained, the flange may be made adjustable. if preferred, as ameans for regulating the lineness of the spray and the amount of waterthrown. A perfect eut off is effected by turning the barrel so thatneither of the openings 13 or 14 in the inner cone will register withopening 5 through the outer cone-as shown, for example, in Fig. 6.

It will, of course, 'be understood that the details of construction maybe greatly varied without departing from the principles of my invention.

I claim- 1. A hose-nozzle consisting of a base, a cone, 3, dependingwithin it. having an opening, 5, a barrel having a chamber, 9, a tubeleading through said chamber, a cone at its lower end closely iittingcone 3. openings in said cone adapted to register' with opening 5, andleading to said chamber and said tube, and a cap-plate engagi-ng saidtube, which closes said chamber with the exception of a narrow circularopening su rrou nding said eapplate.`

2. The base and outer cone having opening 5, in combination with thebarrel having chamber 9, central tube, 15, cone 12, engaging within theouter cone and provided with openings 13 and 14, the latter beingwidened at its central portion for the purpose set forth. and acap-plate nearly closing the outer end of said chamber, whereby partialrotation of the bar'rel will permit water either to pass out through thechamber, producing a circular ribbon-spray through the tube, producing afull stream or a central spray, or will effect a perfect cut-off.

In testimony whereof I affix mysignature in presence of two witnesses.
